c. Starting at the point where the second vector ended, plot the third
vector for the 4,000 to 6,000 meter layer, which represents a wind
with a speed of 18 knots blowing from 1600 mils.
This vector is
plotted 17.3 kilometers long toward 4800 mils. Mark the end of this
vector with the number 6 to indicate 6,000 meter height and add a
small circle (Figure 2-8).
